Do you see that persona on the Firefox/Tools > Add-ons > Appearance/Themes page?

Does that persona have an uninstall button?

If that doesn't help the reset the lightweightThemes on the about:config page 

lightweightThemes.isThemeSelected -> false
lightweightThemes.usedThemes -> (empty string)

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
